Even though I have not read the book, my guess is that this is a great starting point for RIA (Rich Internet Applications -- I had to look that up)

RIA is clearly another buzzword to describe user interfaces that mimic a thick-client application. AJAX is at the core of this type of work.

As I said, I have not read the book so it may not be basic enough for someone with no AJAX exposure. However, if you understand the core concepts of AJAX and can write some AJAX code, my guess is that this is a wonderful book for you to work with. And if you haven't programmed or worked with AJAX yet, I suggest buying a basic AJAX book and then this one for your next iteration of learning.

Good luck!
[Removed not-so-nice portion of this reply. Please refrain from such posts.]

The strength of this book, I hope, is on writing efficient Javascript and Java server-side code (using whatever framework) that makes the best of the notion of AJAX to optimize the speed of the overall user experience.

AJAX is nothing new, even if it took a long time to give it a name, what we're looking for are the ways to make this combination of technologies work together really well to provide a fast and comfortable user experience.

This book claims to be advanced AJAX and I'm curious what types of performance tricks and tips it provides? Are you providing "AJAX architecture" ideas or simple ways of optimizing Javascript for fast HTTP calls? Possibly all of the above.

I'm very curious about this book but I would like to have more information about what type of help it is going to provide me.

Thanks!
I followed a link from java.net to IBM's website for information on emerging web services-related standards like WS-ReliableMessaging, WS-Security, WS-Addressing, among others. I started reading up on them when it became apparent that these "standards" are not really standards at all but rather, are proposals for standards from IBM, Microsoft and "their other partners".

Does anyone have any knowledge on the status of these proposals or what has actually become standardized and through which standards body? (Side question: how can we have "standards" with so many "standards bodies"? What a pain!).

I went to w3.org and perused their web services section and the only standard mentioned there (other than WSDL and SOAP) was WS-Addressing.

If anyone could shed some light on this, I would greatly appreciate it.

Thanks to both of you for your responses to my question. While it creates a small challenge for me, I've definitely learned something fundamental about Java. Thanks!!

I would look this up in a book but I don't think I'll quite find the answer I'm looking for. My question is about overriding a static method. My base class is the following...



Now here is my child class. It only overrides the createFactory method




Unfortunately, when I try to use MyChildUtitlityClass, it still calls MyUtilityClass.createFactory().

So my question I guess is can a child class override the parent class' static method in this situation. I'm not a newbie but I don't often use static constructs such as these. Any advice would be greatly appreciated.

Thanks!

Nevermind... extensive searching this afternoon has revealed an answer to my question. Here are some details for those that care.

For one, it's different for each phone. Some have GPS-enabled chips which support e911 for accessing the coordinates of a phone and others can enable this type of behavior using Bluetooth technology.

Second, some carriers offer the service under limited restrictions and others don't. For instance with Sprint PCS (my service provider), in order to access the API for gps functionality on the phone, you have to either pay for an expensive Verisign certificate or enable certain features on the phone through their developer network.

In short, it doesn't seem to be very easy. Plus, your phone must be MIDP 2.0 compliant.

Many phones provide the capability of relaying position coordinates to rescue services for when 911 is dialed. I know my phone has this capability, although it can be turned off in the phone settings.

Anyway, I was wondering if the J2ME API defines interfaces for accessing this sort of data or would this be something strictly limited to the a phone vendors API? If it's specific to the phone, does anyone know of any phones that offer such an API?

I've never tried to execute a command using the native Runtime but according to the API, your argument to Runtime.exec should be a String array where each element is a token of the command line string. So, instead of...


It should be ...

Does anyone know of any good resources for constraint programming? Either in Java or in general.

This question is really just one of curiosity...

Anyone know of existing API's for interfacing with portable music players like an IPOD? Do the hardware vendors ever offer API's for writing programs to manipulate playlists or anything like that? I can think of a lot of reasons they wouldn't but I was just curious and thought some of you might have some insight on it.

One detail of note, I will probably be deploying this application in a Windows environment. Further, it will be printing to a local printer in all liklihood, not a networked printer.

Stand-alone Java apps, what API's are available for interfacing directly with printers connected to the local machine? I'm accustomed to writing web-based apps so I've never really needed to access a local printer like this. Any direction on this would be greatly appreciated.

I am doing a freelance project to that will hopefully bring the invoicing process between a company and the manufacturer of its products onto the web, rather than using faxes and snail-mail.

I have built my data layer and now I'm trying to build in the business rules. I am hoping to find an open-source workflow engine to integrate into my project. However, I don't want this engine to be too tightly bound to the rest of the application. I plan on integrating Aspectj in eventually but do not want to endure that learning curve for my first release. I've looked at BigBross' Brossa but wanted to get some other ideas.

As I said, I don't want my workflow engine too tightly coupled with the rest of my application. I am planning on configuring it as a JNDI resource even so I don't have to access it through the servlet.

My the basics of my app architecure is as follows...
Stuts -> workflow?? -> JOTM (JTS) -> basic DAO

I'm using Tomcat/MySQL/Windows 2k for my system architecture.

Any thoughts or suggestions would be greatly appreciated! Also, I apologize if I'm being vague at the moment... please respond with further questions about my goals if you think you might have any ideas.

Many thanks!!
